Topic link ：P7222 [RC-04] Informatics competition - Luogu | New ecology of computer science education (luogu.com.cn)

Title Description

Small R Today, I learned the mathematical knowledge about cosine , Please help him calculate the remainder of an angle ！

The remainder of an angle is calculated as follows ：

∠B=90°-∠A

among A Is the given angle ,B Is the angle you want to calculate .

Input format

One line, one integer x, Express ∠A=x°.

Output format

One line, one integer y, Express ∠B=y°. You need to calculate strictly according to the formula .

Examples #1

The sample input #1

100

Sample output #1

-10

Tips

about 100%  The data of ,x  stay C++ Linguistic int  Within the scope of . namely x∈[-2^31,2^31-1].

AC code:（ Don't forget to answer this question long long...）

#include<iostream>

using namespace std;

int main()
{
	long long x; //  Must open long long, otherwise int Boundary operation may explode int！！！ 
	cin>>x;
	cout<<90-x<<endl;

	return 0;
}
